Drenaje venoso pulmonar anómalo parcial del pulmón izquierdo: Corrección mediante toracotomía sin circulación extracorpórea / Partial anomalous pulmonary venous drainage of the left lung: Correction through thoracotomy without extracorporeal circulation

Se describen dos casos de drenaje venoso pulmonar anómalo parcial del pulmón izquierdo a la vena vertical, la cual drena a su vez a la vena innominada, en dos niños de 6 y 8 años respectivamente. Se exponen el cuadro clínico, los hallazgos del cateterismo, la evolución clínica y el resultado postquirúrgico; adicionalmente, se hace una revisión de la literatura.

Two cases of partial anomalous pulmonary venous drainage of the left lung to the vertical vein, which in turn drains to the innominate vein, are described in two 6 and 8 year old children. The clinical picture, catheterization findings, clinical course and postoperative outcome are discussed and a review of the literature is made in addition.

[Severe cyanosis after total cavopulmonary connection, corrected by surgical ligation of the suprahepatic veins]. / Cianosis severa tras derovación cavopulmonar total, corregida mediante ligadura quirúrgica de las venas suprahepáticas.

We describe a patient with a diagnosis of heterotaxia and independent drainage of the suprahepatic veins into the venous atrium who underwent total extracardiac cavopulmonary connection in which hepatic vein drainage remained directly into the atrium. In the immediate postoperative period she showed increasing cyanosis that suggested substantial right-to-left shunt. Surgical ligation of the suprahepatic veins resolved the complication effectively without signs of hepatic congestion or portal hypertension.
